Just got a noname 1GB SD Card, seen on lots of posts that brand is quite important for zaurus, but chanced on a cheap (£40) ebay auction. Card is used - normal usage scoring on contacts.When I insert the card, the SD card icon does not appear

this is the first SD card I've tried, so I can't confirm that the slot works (only have CF and memory sticks in other devices...), but the "Disk change detected" reported in dmesg is promising that the hardware at least works. Can't confirm that the card works elsewhere until tomorrow...
